--  This child package of Ada.Strings.Unbounded provides some specialized

--  direct advantage of the variable length semantics of these strings.

   --  as an unbounded string of appropriate length. If no File parameter
   --  is present, input is from Current_Input.

   --  These are equivalent to the standard Text_IO routines passed the
   --  value To_String (U), but operate more efficiently, because the extra
   --  copy of the argument is avoided.
